1shot at 5 distances Challenge

[Fordevr]

It's simple! Just shot a single target, 1 shot at each distance. 100, 200, 300, 400 and 500yrds. This will make a 5 shot group when your done. Any rifle any caliber any bullet. Try to do it consecutively if possible. Might have to go for a drive to find the appropriate place to do the challenge. Have Fun! Hope to post one today.

Best all around target distance between center of 2 furthest holes. Then just a best vertical group where the wind is taken out of the equation.(measure vertical distance only of 2 furthest holes center to center)

Well I'm both happy and confused with my target. I'll start by saying there was a cross wind right to left so I used the far right targets as a horizontal reference point for all shots instead of the center target, so with the wind all shots would all be on paper.

1st Pic. - Shot Predictions (forgot to take picture before shooting so I already took 2 shots.)
2nd Pic. - Actual Points of Impact.
3rd Pic. - 5 shot target of only 500 yard shots take weeks earlier.
4th Pic. - Reticle in Scope.

100 yards - Aimed 0.8 below center line and right off the bat I was surprised that my 100 yard shot was 1.5+ to the left of where I expected, but the vertical was perfect.

200 Yards - Aimed dead on center because I thought I was zero'd at 200 and it too was left of where I expected 1.5 inches and also 1 inch higher than expected.

300 & 400 Yards - For 300 I aimed at the same line as I did for 100 yards but used my first line down or the 2moa line and for the 400 yard shot I aimed 0.5 inch below center line and used the 2nd line down or the 4 moa line in the scope. I couldn't be more pleased. Pretty much touching the line that the 200 yard shot did. Only the wind was spreading my group but the vertical spread was amazingly tight All was going relatively well....

500 yards - Here's where everything goes wonky. I expected my 500 yard shot to be in line with shots 2-4 but another 3-4 inches left of the 400 yard shot but when I walked up to the target I didn't even see it on paper. Turns out it was about 6 inches low and I'm just blind. 😞 I decided to shoot one more 500 yard shot and used my windage lines in my scope to aim 1 moa right of the top right target and used the same vertical aim point. It also was much lower than I expected but approximately where I though it would be horizontally, assuming the wind must have died down slightly or possibly shooter error of 2inches at 500 is quite probable also.

I then compared it to a previously shot target I shot a few weeks earlier and got even more confused. I aimed 3 inches high using the 3rd line or 6 moa Line in my scope and was only 3-5 inches below it. But doing the same thing today I was 8-8.5 inches below my aim point. (Basically 1 moa at 500 lower than expected. I just can figure out what the difference is for such a big difference of 4 inches lower at the same 500 yard distance. Temperature was about 10 deg C warmer but I don't think that would make a 4 inch difference.

Anyways had fun and can't wait to try it again.

THOUGHTS.

So I realized I didn't say which caliber or bullet I was shooting.
.204 Ruger
Ammo - Federal Premium 40 Gr. Nosler Ballistic Tip
Rifle - Tikka T3 Heavy Barrel Varmint
Scope - Sightron Siii 6-24x50 FFP

After looking at a wind chart I would say a 3-4 mph wind can make sense of almost all the differences in the horizontal differences, I'm not sure why the 100 yard shot was so far left but I'll take it. 1.7 inches left with a 4 mph wind makes sense at 200 yrds.

[Fordevr]

So the difference in weather of about 27 deg F or about 10 Deg C made a 1.5 inch difference. There is still about 2 inches that have me baffled but I have a theory I will look into more tomorrow. Possibly shooting slightly down hill on the one 5 shot group and on flat ground for the challenge target.🤔

I'm really not understanding how you can "group" 5 shots on 5 different targets, particularly when they are set at different distances.

I'm not an expert, but having trouble understanding how this exercise validates consistency of your rifle/load.

Nice thing is, I might learn something here. Very curious what the result tells you.

Only one target. If you can only hit a target at one range then either your ammo is not consistent or your abilities are off. If you know your load, rifle and capabilities you should be able to hit the same spot on a target at all 5 yardages.

My goal is to be able to hit the same spot on a target at all 5 ranges, something I've had difficulty with past 300 yrds

On my target I learned that :
1) a 3-4 mph wind affects my .204ruger bullet by 1.7 inches at only 200yrds which I didn't think it would because it's a fast round. I still need to check that my zero is correct and it wasn't just off by 1.5 inches. My confusion here is my 100 yard shot was further left than expected also. I'm still learning.🙂
2) I need more work at 500 yards.
3) I was able to hit the same vertical line at 200, 300 and 400 yards with only the wind effecting my poi. Once I get a wind meter I can start to adjust for wind also but one step at a time. To be honest I'm happy to hit paper at 500 right now.
4) For factory ammo this stuff shoots amazing out of my rifle.

I think I may have to try this. I'll post my results when she's complete.

I have a friend that does F class competitions and he is going to send a chart that helps you guess wind better without a wind meter.
